WELL-DRILLING MACHINE.

Specification of Letters Patent.

Application filed April 20, 1907.

Patented June 9, 1908.

Serial No. 369,317.

To all whom it may concern:

Be it known that I, HENRY L. HooPEN- GARNER, a citizen of the United States, residing at Shirley, in the county of Tyler and State of WVest Virginia, have invented certain new and useful Improvements in VVell baling or removing cuttings.

The invention hasfor its object to devise a mechanism utilizing force derived from a steam engine or other convenient type of motor and comprising parts enabling such force to be effectively directed and applied according to the special needs of the work or any eXigency incident thereto such as spudding, drawing tools from the well and the like.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings.

While the invention may be adapted to different forms and conditions by changes in the structure and minor details Without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in which:

Figure 1 is a side view of a well drilling machine embodying the invention. Fig. 2 is a top plan view thereof. Fig. 3 is a detail view of the main and spudding shafts show ing the connecting means. Fig. 4 is a detail view of the main and power driven shafts showing the brake cooperating with the former and for transmitting motion to the latter from the engine or motor. Fig. 5 is a detail view of the sand reel shaft and the brake or chock block cooperating with the friction pulley fast thereto. Fig. 6 is a detail view in perspective of a crank arm. Fig. 7 is a detail view of the means for holding the operating rods in an adjusted position.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The operating parts are mounted in a way to admit of the machinery being readily transported from place to place as occasion may require. The frame-work for support ing such parts comprises longitudinal sills or timbers 1 and transverse timbers or sills 2, said parts being rigidly connected in any substantial manner. The framework is mounted upon ground wheels 3, the front axle being arranged to turn in the manner well understood to admit of proper steering of the machine when moving it from one place to another.

For imparting movement to the working elements, an engine 4 of any type is mounted upon one end of the frame-work and power is transmitted from the shaft 5 thereof to the main shaft 6 by means of drive belt 7 which passes around band pulley 8 fast to shaft 5 and band pulley 9 fast to shaft 6. A pinion 10 is loose upon the shaft 6 and is provided on one side with a half clutch 11 either formed with or connected to said pinion so as .to turn therewith. A sleeve 12 is slidable upon the shaft 6 and is connected thereto by means of a feather and spline so as to rotate therewith and is provided upon the end facing the pinion 10 with a half clutch 13 matching the half clutch 11 so that when the two half clutches 11 and 13 are in mesh, the shaft 6 and pinion 10 will rotate together. A shaft 14 arranged parallel to the shaft 6 is journaled in bearings applied to the frame work and carries a gear wheel 10 adapted to mesh with the pinion 10. When the clutch sleeve 12 is moved away from the pinion 10 to unship the clutch members 11 and 13, the shaft 6 will continue to rotate without imparting any movement to the shaft 14. The

shaft 14 is adapted to receive the rope, not shown, by means of which the several tools are operated. A brake wheel 15 is fast to an end portion of the shaft14 and cooperates with a brake band 16 which is secured at one end to a rod or bar 17 and has its opposite end connected to the crank portion 18 of a shaft 19 mounted in bearings applied to the framework and having an operating handle 20. By proper manipulation of the handle 20, the brake band 16 may be caused to grip the brake wheel 15 more or less tightly to control the rotation of the shaft 14 and the paying off of the operating rope or cable wound thereon. When the. shaft 14 is positively driven to wind up the rope as when drawing tools, casing or the like from the well, the brake band 16 is slack so as not to offer any resistance to the free rotation of the brake wheel 15 and shaft 14.

For operating the drill, a walking beam 21 is provided and mounted in bearings at the upper end of a 1post 22 rising from one side of the irame-wor end of the walking beam 21 is adapted either to have the temper screw connected therewith or suitably supplied with means for operating the drill rope or cable. The opposite end of the walking beam is connected by pitman 23 with a crank 24 fast to the outer end of the shaft 6. The wrist pin 54 connecting the pitman 23 with the crank 24 is adjustable upon the crankto provide for varying the oscillation of the walking beam andthe stroke of the drill, the said wrist pin being adapted to be inserted in .a selected one of the openings 55. When drilling, the clutch 'sleeve 12 is moved to unship the clutch members 11 and 13 so as to impart no positive movement to the shaft 14. For moving the clutch sleeve 12, a-shipper lever 25 is provided and fulcru med at 26 upon a cross bar 27, a rod 28 connected to one end of the shipper lever extending within convenient reach to admit of ready operation of the shipper lever to throw the clutch in or out of gear as may be required.

The sand reel 29 is mounted upon a shaft 30 arranged transversely of the frame-work and parallel with the shafts-6 and 14, one end of the shaft being mounted in a bearing 31 applied to one side of the frame-work, and the opposite end portion of the shaft 30 being mounted in a lever 32 pivoted at 33 to the opposite side or sill of the frame-work. The shaft 30 is mounted to have a limited swinging movement with respect to the bearing 31, whereby the shaft may move with the lever 32 which is essentialto control the movements of the shaft and the sand reel mounted thereon. A pulley 33 fast to an end portion of the shaft 30 is adapted to make frictional contact with either band pulley 9 or a brake block 34 firmly attached to the sill 1 supporting the lever 32. Then the lever 32 is moved in one direction to bring the pulley 33 a in engagement with the pulley 9, the shaft 30 is positively rotated to wind up the rope, not shown, upon the reel 29, thereby lifting the bucket commonly employed for baling the well or removing cuttings. Upon moving the lever32 in the opposite direction, the pulley 33 may be brought into contact with the brake block 34 with a greater or less friction so as to control the descent of the baler or sand bucket into the well. For operating the lever 32, a rod 35 is employed and extends within convenient reach of the operator, said rod having an end portion 36 conand suitably braced. One

nected thereto by means of a swiveljoint 37 to admit of said end portion 36 being turned to accommodate itself to the hand of the operator as may be required. The end portion 36 of the rod 35 is formed with a series of teeth 38 which are adapted to be engaged to, whereby the fishing tool is reciprocated or jigged in the well. A crank 43 is fast to the outer end of the shaft 40 and is adapted to be connected by means of itman 44 with the crank 24 of shaft 6 a ter said crank 24 has been disconnected from the pitman 23. When the two cranks 24 and 43 are connected as shown in Fig. 3, motion is imparted from shaft 6 directly to shaft 40, the latter being oscillated to impart a corresponding oscillatory movement to the crank 41, whereby the spudding or igging of the tool in the well is. accomplished. A. snatch block 45 is provided at one end of the frame-work for the operating rope or cable to pass over during the spudding operation.

From the foregoing, it will be understood that the machine is adapted for the various operations incident to boring or drilling deep wells. When drilling, the walking beam 21 is connected to the crank 24 as indicated in Figs. 1 .and 2, the inion 10 being disconnected from the sha t 6 by unsh-ipping of the clutch members 11 and 13 to permit the rope to unwind from the shaft 14. To draw the tool from the well, the rope is disconnected from the walkin beam in the usual way and the pinion 10 is c utched to the shaft 6, thereby imparting positive movement to the shaft 14 upon which the ro e is wound. When lowering the tool into t e well, the pinion 10 is disconnected from the shaft 6 by throwing the clutch sleeve 12 away from the pinion 10, the descent of the tool being regulated by proper manipulation of the lever 20 to cause the brake band 16 to grip the brake pulley 15 more or less tightly. For spudding, the walking beam is disconnected from the crank 24 and the cranks 24 and 43 are connected by the pitman 44, it being understood that the crank 24 is considerably shorter than the crank 43 to admit of rotation of the crank 24 so as to impart an oscillatory movement to the crank 43. The rope after being engaged with the wrist pin 42 of the crank 41 and after being passed over the pulley of the snatch block 45 is alternately tugged upon and relaxed with the result of im arting the jigging movement necessary for t e spudding operation. when descending into the well by pressing the pulley 33 against the brake block 34. When it is required to withdraw the 'baler from the well, the pulley 33 is pressed into contact with the pulley 9. When it is required to reverse the engine, as in drilling and raising and lowering casing, the same may be effected by means of a rod 46 which passes through the post and is provided with a series of teeth 47 for cooperation with a pawl 48 similar in operation to the pawl 39.

A cord, not shown, extending from the throttle valve or lever of the engine is adapted to pass over or to be connected with a pulley 49. The several controlling devices are located within convenient reach of the operator from the most advantageous point as shown most clearly in Figs. land 2. At or near the well is located a mast 50 which is of sectional construction for convenience of handling and storing, said mast being braced by suitable guys 51. A crown pulley 52 is provided at the outer end of the mast for the operating rope to pass over during the drilling and spudding operations. A second pulley 53 is provided near the top of the mast and at one side thereof for the sand rope to pass over.

Having thus described the invention, what is claimed as new is:

The herein described well drilling machine comprising a frame-work, a transverse shaft 6 journaled thereon, a drive pulley 9 rigid with the shaft, a pinion 10 loose upon the shaft and provided with a half clutch 11, a sleeve 1 2 rotatable with the shaft and slidable thereon, the said sleeve being formed with a half clutch 13 matching the half clutch 11, a cross bar 27, a shipper lever 25 pivoted upon the cross bar 27 and engaging the sleeve 12 to move the half clutch 13 into and out of engagement with the half clutch 11, a second shaft 14 disposed parallel to the shaft 6, a gear wheel 10 a mounted upon the shaft 14 and meshing with the pinion 10, a brake mechanism cooperating with the shaft 14, apost 22 projecting from the frame-work, a walking beam 21 mounted upon the post, a crank 24 rigid with the shaft 6, a pitman 23 for detachably connecting the crank 24 to the walking beam during the drilling operation, a shaft 40 j ournaled upon the frame-work parallel to the before mentioned shafts and provided with a crank 41 for spudding, a second crank 42 rigid with the shaft 40, a pitman 44 for connecting the cranks 43 and 24 during the spudding operation, a fourth shaft 30 parallel to the before mentioned shafts and provided with a sand reel, one end of the shaft 30 being journaled in the framework while the opposite end is journaled in the lever 32, a pulley 33' upon the shaft 30, a brake block 34 mounted u )on the frame-work on one side of the said pulley, means for operating the lever 32 on one end of the frame-work for throwing the pulley 33 either into contact with the brake block 34 or the pulley 9 upon the shaft 6, and a snatch block at one end of the framework to receive the operating cable during the spudding operation.
